2026-2027!! actual exam preparation document with verified

INTRODUCTION
This document is an important and very helpful preparation
resource for ITSCM 306 CH QUESTIONS AND CORRECT
ANSWERS 2026-2027!!. Every item uses a focused exam stem,
four response options, a keyed response, and a clear rationale,
making it easier to understand the subject, spot distractors, and
build real exam confidence.

, Question 1
A process-mining log shows that 38% of purchase orders loop between
'Approve PO' and 'Reject & Return' at least twice, and the median loop count is
2. Which redesign intervention most directly addresses the root structural cause
rather than its symptom?
A. Automate the 'Approve PO' task with an RPA bot to reduce human
handling time.
B. Add a pre-submission validation gateway that enforces budget and
vendor-master checks before the approval task.
C. Increase the approval authority threshold so fewer POs require
manager review.
D. Reassign the approval task to a centralized shared-services team to
reduce variance.
Correct Answer: B - Add a pre-submission validation gateway
that enforces budget and vendor-master checks before the
approval task.
RATIONALE
Repeated loops between approval and rejection indicate defective
inputs entering the approval task (missing budget/vendor validation),
so inserting a validation gateway before approval removes the root
cause. RPA, threshold changes, and centralization address symptoms
(handling time, volume, variance) without preventing invalid POs
from looping.
Question 2
A global retailer runs a single-instance ERP in one region but requires sub-100
ms read latency for store POS lookups across three continents. Which
architecture best resolves the CAP trade-off for this read-heavy workload?
A. Two-phase commit across all regional ERP nodes to guarantee
linearizable reads.
Page 2
, B. A single primary with synchronous cross-region replication and local
read replicas with bounded staleness.
C. Full multi-master active-active writes on the ERP database with
last-writer-wins conflict resolution.
D. Batch nightly replication of the ERP database to each region's
read-only copy.
Correct Answer: B - A single primary with synchronous
cross-region replication and local read replicas with bounded
staleness.
RATIONALE
A single primary with synchronous replication preserves write
consistency, while local read replicas with bounded staleness satisfy
the sub-100 ms read SLA and accept a controlled consistency
trade-off. Full multi-master (C) risks divergent inventory writes; 2PC
(A) adds cross-region latency that violates the SLA; nightly batch (D)
is far too stale for POS lookups.
Question 3
A data warehouse team must load 4 TB of daily clickstream data while
preserving referential integrity with a slowly changing dimension (SCD Type
2) customer table. Which ETL pattern is most appropriate?
A. Full truncate-and-reload of the customer dimension each night to
simplify logic.
B. Change data capture on source systems feeding a staging area, then
merge into the dimension with effective-dating and surrogate keys.
C. Directly overwrite dimension rows in place using natural keys as the
primary key.
D. Load clickstream facts first and backfill dimension keys in a weekly
batch.
Correct Answer: B - Change data capture on source systems
feeding a staging area, then merge into the dimension with
Page 3
, effective-dating and surrogate keys.
RATIONALE
SCD Type 2 requires versioned rows with effective dates and
surrogate keys, which is achieved by CDC into staging then a merge
that closes old versions and opens new ones. Truncate-reload (A)
destroys history; in-place overwrite with natural keys (C) cannot
represent versions; loading facts before dimensions (D) breaks
referential integrity and star-schema joins.
Question 4
A hospital's NIST CSF 2.0 assessment shows strong Identify and Protect
functions but weak Detect and Respond. A ransomware incident encrypts
backups because they were network-accessible. Which control gap most
directly explains the failure?
A. Insufficient asset inventory under the Identify function.
B. Absence of network segmentation and immutable, offline backup
copies under Protect and Recover.
C. Inadequate security awareness training under Protect.
D. Missing vulnerability scanning under Identify.
Correct Answer: B - Absence of network segmentation and
immutable, offline backup copies under Protect and Recover.
RATIONALE
The scenario describes backups reachable from the compromised
network, which is a Protect/Recover control failure-immutable,
segmented, offline backups are required to resist ransomware
encryption. Asset inventory, training, and scanning are relevant but do
not explain why backups were encrypted; the gap is backup isolation
and segmentation.
